Revision 1.0 schematic for the Compal LA-9868P mainboard, stored as a 1.26 MB RAR archive. The name gives only the Compal board code, with no laptop brand, model, CPU or GPU, so confirm the machine by the number printed on its PCB. After extraction the diagram lets a technician follow the power-on chain from the adapter input through the charger and EC to the CPU core regulators, locate test points and check for shorts. Make sure the board revision matches before trusting resistor values or part options.
